Abstract
Disclosed is a display device and, more particularly, a micro-shutter display device including: a light source emitting light; a lower substrate having an optical conversion unit performing at least any one of a function of converting back light output from a light source into primary colors corresponding to sub-pixels and a function of reflecting ambient light having a primary color band corresponding to sub-pixels; a micro-shutter opening and closing a path of light output from the optical conversion unit; and a driving circuit supplying a driving signal to a movable unit electrode or a fixed counter electrode, wherein the micro-shutter includes: a shutter micro-structure comprised of a shutter blade blocking light output from the optical conversion unit and a shutter aperture allowing light output from the optical conversion unit to be transmitted therethrough; an elastic element connected to the shutter micro-structure to provide elastic restoring force when the shutter micro-structure structure is driven; a movable unit electrode configured to be connected to the shutter micro-structure; and a fixed counter electrode spaced apart by a certain interval from the movable unit electrode.
